The single row tapered roller bearing has an outer ring, its inner ring and a set of tapered rollers are an inner ring assembly enclosed by a basket-shaped cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing external dimension standard, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve internationality with the same type of outer ring or inner ring assembly exchange. That is to say, in addition to the external dimensions and tolerances of the outer ring of the same model, which must comply with the requirements of ISO492 (GB307), the cone angle and component cone diameter of the inner ring component must also comply with the relevant regulations for interchange.
Generally, the tapered angle of the outer ring raceway of a single-row tapered roller bearing is 10°~19° before it can bear the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to withstand axial load. Bearings with large taper angle, add B to the rear code, and the taper angle is between 25°~29°, which can bear larger axial load. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation.
The outer ring (or inner ring) of a double-row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, with a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre-interference of the double-row tapered roller bearing.
Four-row tapered roller bearings. The performance of this type of bearing is basically the same as that of double-row tapered roller bearings, but it bears greater radial load and lower limit speed than double-row tapered roller bearings. It is mainly used for heavy machinery, such as Rolling mills, etc.
Multi-sealed double and four-row tapered roller bearings, ZWZ provides long-life, multi-sealed double and four-row tapered roller bearings. Carry out a new and personalized design of the bearing, change the traditional design method of fully sealed bearing, and adopt a new type of sealing structure that combines sealing and dust prevention to improve the sealing effect and improve the sealing performance. Compared with open structure bearings, multi-sealed double and four-row tapered roller bearings have an increased life span of 20%-40%; lubricant consumption can be reduced by 80%.
